how is the value coming after type promotion?

Question

In a type promotion example I am getting the output as 515.

I know that the value of char c (which is 'a') after it gets promoted to an int; but on what system is the value of char decided while promoting it to int?

public class Main {
    public static void main(String args[]) {
        char c = 'a';
        int i = 50000;
        int result = i / c;
        System.out.println("i / c is " + result);
    }
}

Answer 1

c is converted to its ASCII value of 97.

So, 50000 / 97 ~= 515 because of integer divisions (no floating decimals obtained in the result).
